Abstract
This paper reports the crystallization behavior of maleic anhydride grafted poly(propylene) (PP-MA) with an aryl amide derivative (TMB-5) as β-phase nucleating agent (β-NA). The isothermal and nonisothermal crystallization behaviors of PP-MA and nucleated PP-MA are comparatively researched based on the concentration of β-NA of 0.2 wt%. Subsequent melting behaviors after isothermal and nonisothermal crystallization process are also investigated to explore the crystalline structures formed during the crystallization. The results indicate that TMB-5 is an efficient β-NA in influencing the crystallization of PP-MA through increasing the crystallization rate and decreasing the fold surface free energy, leading to large amounts of β-phase formation during the crystallization process.
